Shipping guide
Shipping with dry ice: pack it, label it, send it
Dry ice keeps parcels frozen, but it is regulated as a dangerous good. This guide covers the basics for senders.
Shop dry iceFour steps to a compliant parcel
- Choose the quantity.
Allow for the longest likely journey plus delays. Insulation, parcel size and outside temperature all change how fast dry ice is lost. - Pack so gas can escape.
Use an insulated box that is not gas-tight. Pack the payload tightly so it cannot move as the dry ice shrinks. - Mark and document it.
Label the outer box UN1845 with the net weight of dry ice, and complete the paperwork your carrier asks for. - Brief the recipient.
They should expect the parcel, open it somewhere ventilated and know how to handle it.
How much dry ice should I use?
There's no single answer. Work through these four factors, or ask us and we'll suggest a quantity.
A
Journey time
Door to door, including collection, sorting and a delay buffer.
B
Box and insulation
Thicker insulation means slower loss. Poor insulation needs more dry ice.
C
Payload
Its size, starting temperature and how cold it must stay.
D
Form
Blocks last longer. Pellets and slices fill gaps around the payload.
